A structure access system that allows a user at ground level to open and close a traditionally ladder-accessed entrance on the top of a structure like a silo through a pivotable lever-controlled linkage that includes elongate members joined by a rocker arm configured to translate vertical movement into angled movement to open and close the top entrance.

A cargo container is disclosed which contains a bottom side; a front side; a back side; a central frame connected to the front side, the back side, and the bottom side, dividing the cargo container into a multiple storing areas; a left top wing-shaped door, hingedly connected to a top of the central frame, operable to open and close down to one and a half height to the central frame; a left bottom wing-shaped door, hingedly connected at a one and a half height of the central frame; a right top door, hingedly to the said half height distance to the mid-section frame; and a right bottom door, hingedly connected to the central frame at the one and a half height of the central frame and close down to the bottom side.

A system for covering fluid containment tanks to contain vapors and minimize evaporation of the vapors into the surrounding atmosphere. The system includes a flexible cover and restraint elements, guiding rails which support the cover over a tank and provide guidance for extending and retracting the flexible cover, a belt drive extends the leading end of the flexible cover and a drivable drum provides a way to retract the flexible cover and upon which the flexible cover will be rolled and stored, and a method to locate tank elements beneath the flexible cover system to prevent operating interferences.

A bulk material transport system includes one or more bulk material transport bins, weighing platforms, and vehicles arranged in various combinations as bulk material transporters, assemblies, and units. The system is useful for coupling with a bulk material container, forming a reduced pressure region at an inlet of the transport bin, and dispensing bulk material into the transport bin through the reduced pressure region.

A bulk material discharging system includes a transmission station including a transmitting vessel having a transmitting vessel inlet configured to receive bulk material from an outlet of a bulk material transporter, and a transmitting vessel outlet to transmit bulk material therefrom. The system also includes a transporter handling station located operatively upstream of the transmission station and including at least a portion of a transporter handler including at least one carriage with transporter couplings configured to engage corresponding carriage couplings of the bulk material transporter and configured to convey the bulk material transporter over the transmitting vessel.

An arm assembly for a cover system includes a force mechanism associated within a hollow arm of the assembly that includes a resiliently compressible element, such as a compression spring or gas spring, connected to one end of a cable. The opposite end of the cable is fastened to a non-circular pulley mounted to the container body, so that the cable is wound around the pulley as the arm pivots relative to the container body. As the arm pivots in a stowed direction, energy is stored by the compressible element, and releasing the stored energy causes the arm to pivot toward an extended or deployed position.
